"ipsec down" tries to gracefully close the tunnel, sending a DELETE
message. As there is a DPD exchange in progress, with IKEv2 and a window
size == 1, that message has to be queued.

One could just remove the IKE_SA state without notification, but this is
not what "ipsec down" does. Unfortunately, there is currently no
mechanism to immediately delete such an IKE_SA.
